Background: The aim of the present study was to determine whether instructors could accurately assess chest compression quality visually, considering the association between chest compression depth and rate.
Methods and results: In this prospective, observational study, the quality of chest compressions performed by a simulated actor in a video was visually assessed by certified instructors. The film consisted of 14 case scenarios, each including a combination of depth (2 patterns: adequate, 5-6 cm; and inadequate, <5 cm) and rate (7 categories: compressions 90-150 times/min in increments of 10 times/min).
